GPU Driver & Documentation #2

Open kamilion opened 1 year ago

kamilion commented 1 year ago

Howdy, I've been looking through the datasheets and product briefs, and I haven't been able to find any information at all about GPU support.

All I've been able to discover so far has been https://github.com/starfive-tech/VisionFive2/tree/JH7110_VisionFive2_devel/soft_3rdpart/IMG_GPU/out

Where is the source for this driver located?

MichaelZhuxx commented 1 year ago

the driver is here https://github.com/starfive-tech/linux/tree/JH7110_VisionFive2_devel/drivers/gpu/drm/img

kamilion commented 1 year ago

Thanks! Are the userspace support components to go along with the kernel driver also available from another repository?

MichaelZhuxx commented 1 year ago

yes, userspace is the link you have pointed out

No, I mean, the supporting library support for accelerated graphics on top of the kernel DRM layer. X11, wayland, and vulkan? I don't recall seeing any Imagination support hitting the MESA tree recently...

I've just spent the last ten minutes pouring over these generated register definition headers, with Imagination MIT+GPL2 headers. Looks good, and fairly complete to me; when is this generic KMS support for what appears to be ~35-40 device variants going upstream, if I may ask?

Since AMD's been submitting generated register headers for quite a while now, I don't expect that to be as big of a problem as it was a decade ago, when the PowerVR work was being evaluated.

Edit: Ugh, okay, I've just unpacked the tarball and discovered what I feared; all of the accelerated graphics support is binary blobs.

This is going to be a nightmare for me to get working with lubuntu's packaging...

Oh well. Off to go start writing python scripts to get ready for my board to arrive from ameridroid.

It seems that at least soft_3rdpart/IMG_GPU/out/img-gpu-powervr-bin-1.17.6210866.tar.gz on HEAD is not what the build system expects.

Reverting it to a2c06b2c54c18961087d6caa834d6936e9862af9 helps.

It's unfortunate that we'll need blobs to drive the GPU...

hi kth5, it also the git lfs issue, please see the issue [](url)

jackffmm commented 1 year ago

I will not buy this device untill it has blobs.

coderamen666 commented 1 year ago

That's on you bud. Imagination is actually working on making an open Mesa driver for 3d acceleration. The video hw acceleration is open source however.

It's unfortunate. Agreed. But open GPU drivers are planned to replace these blobs.

ok @jacobrogers256 but why not to release what they have now, so the development can be much faster and better ? look how the community improved the intel drivers.

I agree. It's just that IP law is draconian and the corporations take advantage of this to squeeze as much profits as possible from people while revealing as little as necessary about their products.

my StarFive VisionFive 2 cannot boot StarFive's official images, it can only boot DietPi's build for the VF2. How can I install this driver on DietPi? DietPi is based on Debian
